I am not a runner, but I've been really interested in minimal shoes since last Spring, and I barely wore shoes at all over the summer. I'm loving it! But I'm a college student in Michigan, and my campus gets really icy in the winter. Last year, I wore a pair of sneakers most of the time, and Ugg boots (with a thick sole and about 5 mm drop) when there was more than 2 inches of snow. I want to wear more minimalist shoes this year, but I need a boot that has good traction on ice (there really isn't any way to avoid it on campus). I have a pair of Merrell Contour Gloves that I loved through the fall, but as soon as it snowed, I was sliding all over the place! Now I'm back to wearing my Uggs. :/
Also, I've been trying to update my style (I'm turning 26 in a couple weeks and still dressing like I did in high school), so bonus points for something that looks nice enough to wear when I need to dress professionally or I'm going on a date. (That overly sporty look is fine when you're exercising or running errands, but in some circumstances, it just doesn't fit.)
There are not a lot of shoes out there with studs in them that I am aware of. The only ones I have tried are the Inov-8 ORocs, which may not be your thing as they aren't terribly minimalist and are very sporty.
One thing you could consider however is finding a shoe you like with enough rubber in it that you could put your own studs on. La Sportiva sells a kit that allows you to put studs in any shoes you want. Here is the link:

Of course studs like that won't work well indoors!
You could also go with something like Microspikes which you can slip on/off any shoes you like depending on the conditions:

Hope this helps!
